Hand held workout bar with rotating weights

ABSTRACT

A hand held workout bar with rotating decagon shaped weights that have cutouts to affect weight distribution.

A portion of the disclosure of this patent document contains material to which copyrights are made. The copyright owner has no objection to the facsimile reproduction of by anyone of the patent document or the document disclosure as it appears in the Patent and Trademark Office patent file or records, but reserves all other copyrights whatsoever.

The mechanical function of this invention uses the centrifugal force of rotating weights. The weights are attached in the same position on the end of the bar and connected internal by a steel shaft through the center of the bar that is held in the hands of the user. The bar that is held is a steel tube with bearings in the end sleeves. The internal steel shaft with the weights attached turns inside the bearing. Once held and worked in a circular motion by a person the weights will start spinning. The higher the Revolutions per minute the greater the force against the person using it resulting in a cardio and strength training workout at the same time.

BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention relates to hand held dumbbells such as those found in gyms useful in body building.

2. Background Information

Hand held rotating dumbbells are popular with body builders. However existing hand held rotating dumbbells are somewhat irregular in the impact felt when in use by a bodybuilder. Some have addressed this with adjustments for fine tuning.

As will be seen from the subsequent description of the preferred embodiments of the present invention the present invention has significant advantages over prior art.

BRIEF SUMMARY OF THE INVENTION

The preferred embodiment of the present invention uses the centrifugal force of rotating weights. The weights are on the end of the bar and are offset. The weights are attached and connected internally by a steel shaft through the center of the bar that is held in the hands of the user. The bar that is held is a steel tube with bearings in the end sleeves. The internal steel shaft with the weights attached turns inside the bearing. Once held and worked in a circular motion by a person the weights will start spinning. The higher the revolutions per minute the greater the force against the person using it, resulting in a cardio and strength training workout at the same time.

FIG. 1 illustrates an alternate embodiment the present invention.

FIG. 2 illustrates a rotating weight.

FIG. 3 illustrates a preferred embodiment of the invention with a side view of the preferred embodiment of a rotating weight.

FIG. 4 illustrates the preferred embodiment of the rotating weight.

FIGS. 5 and 6 illustrate rotating weights with a dimensional grid.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1, 2, and 5, the alternate preferred embodiment of the present invention, a hand held workout bar 10 comprises rotating weights 1, a steel shaft 2, a flange bearing 3, sleeves 4, a steel tube 5, and a bearing 6.

Referring to FIGS. 3, 4, and 6, the preferred embodiment of the present invention, a hand held work out bar 10A comprises rotating weights 1A, the steel shaft 2, the flange bearing 3, sleeves 4, the steel tube 5, and the bearing 6.

The rotating weights 1A from FIG. 3 as illustrated on FIG. 4 comprise a decagon shape with a cutout 7 for weight distribution and an aperture 7 through which the steel shaft 2 is inserted. The decagon shape weights 1A measure, in the preferred embodiment, 6 inches across the flats 7A. The decagon shaped weight has a full 360 degree range of rotation.

The concept arose while carrying a 54 lb 5 foot banded bundle of small diameter flimsy wire ties. When walking it would start bouncing and rotating on the ends.

Assembly Hand Held Workout Bar with Rotating Weights

Step 1. Insert bearing (#6 FIG. 1) into the Sleeve (#4 FIG. 1)

Step 2. Insert bearing (#3 FIG. 1) into the end of Sleeve (#4 FIG. 1)

Step 3. Place sleeves with bearings on end of tube (#5 FIG. 1)

Step 4. Press Sleeves onto tube, Tube will rest against inside bearing.

Step 5. Insert ½″ steel shaft (#2 FIG. 1) through both sleeves.

Step 6. Press rotating weights (#1 FIG. 1 or #1A FIG. 3) onto ½″ Shaft.

Step 7. Align both weights to same position on each end of bar.

Step 8. Weld weight to end of ½″ steel shaft.

Although the descriptions above contain many specificities, these should not be construed as limiting the scope of the invention, but merely providing illustrations of some of the preferred embodiments of the invention.

It will be obvious to those skilled in the art that modifications may be made to the embodiments described above without departing from the scope of the present invention.

As an example, FIGS. 5 and 6, with the dimension chart are shown as approximately 6 inches across the parallel flats. That dimension can vary.

Thus the scope of the invention should be determined by the appended claims in the formal application and their legal equivalents, rather than by the examples given. 

I claim:
 1. A hand held workout bar with rotating weights comprising: decagon shaped rotating weights with a cut out for weight distribution, a) a steel shaft supporting the at least one decagon shaped rotating weight, b) at least one flange bearing, c) sleeves, d) a steel tube, and e) at least one bearing, wherein the decagon shaped rotating weight has a full 360 degree range of rotation, wherein the at least one bearing is inserted into the sleeve, wherein the at least one flange bearing is inserted into the sleeve, wherein the sleeve with bearings is placed on the end of the tube, wherein the sleeves are pressed onto the tube, wherein the tube will rest against the at least one bearing, wherein the steel shaft is inserted through both sleeves, wherein the weights are pressed onto the shaft, wherein both weights are aligned to the same position on each end of the shaft, and wherein the weights are welded to the shaft.
